MIXER FOR INTERNAi-GOMBUSTION ENGINES OR THE LIKE.

V Specification of Application filed June 30,

T 0 all QUIZ-0772,61? may concern:

Be it known that I, WALTER C. WEST- AWAY, a citizen of the United States, resid ing at Belvidere, in'the county of Boone and State-ofIllinois, have invented certain new and useful Improvements in Mixers for lnternal combustion Engines or the Like.

My invention belongs to that generalclass mixing or co-minglingthe charge of fuel Supply for internal combustion engines, and

-relates particularly to an auxiliary mixer adapted to be placed Within the engine cylinder, or in close proximity to the intake I port, to completely. or finallyco-min-gle or mixthe ingoingfcharge or mixture. It is preferably. used in connection with the. usual 3 form of carbureteror mixer to further mix or complete the mixing; biit-I donot'w-ish to be understood as' limiting. myself to the use of a carburetei', or any; particular type of apparatus for that purpose, or'to an engineso equipped;

- My invention has among its objects the production of a mixer. that is simple; efli .cient,diira'ble and satisfactory, lthat'may be economically tman ifac-tnred and. installed,

that is. adapted for any type of n ine ,and not 'confined to any particular of fuel,

but may be used wherever found applicable.

Referring to the drawings, and particuj larly Figs. 1,2 and 3, 1 represents the walls 7 of the engine cylinder, 2 the cylinder head, 3 the intake port,4.the exhaust port and 5 the piston. Any suit-able form of'ignit-ion' means may be provided, the same being rep resented by a-spark plug 6. A four-cycle type of engine is illustrated in F ig'. 1, the intake port being controlled by avalve 7 1 arranged to seat on a suitable-valve seat 81 formed infthepart 9, which maybe made" integral with the cylinder Walls if desired. The valve in the' exhaust port is notshown. Theyalve 7 is provided with a stem 10, which'extends through a casing 11 secured tothe engine cylinderby bolts 13 passing. through... the flange 12 and engaging the cylinder' .ngalls; The casing 1 1 is provided with. a chamber 1 L therein and With an inlet l9 ,,.through which the mixture or charge is admit-ted from. a 'pipe 20, or its equivalent, ,frofmthe carbu reter or other mixing means. i' Tile-waive ..*is normally maintained on its seat by a resilient member 17 .engag' :i11fg .the -11,.ai1 d' a. collar- 15, which is secured ton tlielstem- 10 by a pin 16. l Ifdesired, a g o'lla r loamy. be'lpr ovided tor-limiting the merely. for illustration.

so that the shell is substantially closed at its ends. Through the walls of' the shell are provided a plurality of openings 31, the same being preferably in the form of narrow circumferential extending slots,'or apertures. Where the mixer is arranged in substantiall y the position shown, the slots in the under side may be omit d so as to collect any particles of hydro-carbon. Preferably arranged within the shell is a spreaderor distributer 105.

The operation of the device is substantially as follows: As the valve 7 is opened,

' either mechanically or by the suction of the described, is

engine, ture 'passes through the and the seat 8, and into thechamber 30' in the mixer; thence about the spreaderor distributer 105 and out through the openings 31 to the interior of the cylinder ,f w liere it is compressed, fired, and the products of combustion discharged infth e usual. manner. As the charge passes through the slots .31 it is further broken up and mixed or'comingled, greatly improving the mixturen As previously V mentioned, the mixture is preferably passed through a carbureter (not shown) before its passagefrom the' pipe 20 into the casing chamber 14:, but I do not.

wish to be understood as limiting myself to a carbureter orother mixing means. Inthe case of some kinds of mixtures, where a certain amount of pre-heating beforefiring improves the charge,

in the chamber" 30 in the mixer, which is warm or hot from the explosions in the cylinder'. With this 'constructien-Mthe mixer moves back and forth with'the valve,the one outlet from the shell being through the of slots 40 in the end 36. The operation of the same is substantially the same as the mixer described.

.In Fig. 6 is illustrated a slightly different form of mixer, applicable for use where the intake valve is arranged to seat in a suitable casing on the cylinder. Referrin to the figure, 45 represents the cylinder wal 46' the cylinder head, 47 the piston and A8 'thei'ntake port, the exhaust port, ignition mechanism, etc.,'being omitted. In this case the casing 51;is provided withavalveseat to take in a fresh charge, the mixchamber 14 in the v casing'll and past the valve between itsface:

it will be readily seen [that the same is efficiently 'pre-heated while s39 in the sides. or wall ofthe,

' terior 50, upon which the valve 49 seats. It is, of course, understood that the casing 51 may extend as far through the port 48 as may be desired, and the valve seat consequently be as shown, or farther intheintake port. The 'valve 49 isprovided' with" the stem 55 and with the resilient member 61,'cap' 59, pin

.andv stop 62 similar to the, construction previously described. The-easing 51 is provided'with a chamber 56 having an inlet 57, through which the incoming mixture is ad mittedfrom the pipe 58. The operation of the valve is heretoforejdescribed, that is it may be operated mechanically or bythe sue '-tion of the engine. In this case, however,

the mixer does not move with the valve. The mlxer comprises a shell 64 having an end65,

"the walls being provided with openings 66,

which are preferablyas' shown. "Openings vmay be provided in the end 65similar to the openings in themixer shown in Figs. 4; and

5, if desired. .In this case the mixer end 1s flangedfa's at 6'7 and threaded to en age the cylinder wall, and preferably provided with a spreader 106.. Any equivalent means for securing it in position, however, may-be employed, as'for example, to the casing 51 when extended as before mentioned. The mixture 1s further mixed or co-mingled with this form in 'a similar manner to that described heretofore in reference to the construction shown in/Fig. 1.

Figs. 7 and 8 illustrate the application of" the mixer to a two-cycle engine, the same, however, being merely to illustrate 'itsapplication, as the mixer is substantially simi- In this form 7.5 is the intake passage,.separated from the water'jacket'by a partition 72, 7 1 being the intake port. The mixer comprises ashell 76 having an end 77 and provided with openings 78 through which the mixture passes. The mixer maybe secured in position in any-desiredway; As shown, it is threaded at 79 'and arranged to engage the extended portion 80 in the cylin-- der wall,'there being a space 81 between the sides of the shell and the wall of the intake port. In operation the'mixture or charge passes from the intake passage 75 to the in of the shell, and thence through the openings '78, through the spaces Slj and through the intake port to the interior of the cylinder. The mixture is improved asfh'er'etofore described, therebeing' a slight heating of the mixture as mentioned. A spreader similar to those previously described may be employed if desired. 1

The form shown'in Figs. 9, 10 and' 11 is somewhat different in construction, but the action or result is substantially similar, the

100' l'arto that shown in 'Fig." 6. Referring to these figures, 69 represents the cylinder wall intake and exhaust may be provided.

In these figures 84 represents the engine cylinder provided withJ-the usual head 85, piston 86, intake The valves contnolling the; intake and exhaust are not illustrated, as they may be of any desired form, or substantially similar to the intake valve herein described. Arranged within the cylinder, preferably proximate the head, is a transverse partition or part 89,

' the same being arranged to screw in the end,'or to be otherwise secured in position. The part 89 is extended as at 90, the same forming aring and is of sufiicient height to fit tight against the cylinder head. 85 when i I the same ispositioned. The part 90 is provided withopenings 91 on the side at the intake port 87, 92 being a support or brace,

which may be provided if desired. ranged on the interior of the part 89 and its extension 90, is a part 93, the same being shown as arranged to engage the part 9O and be supported thereby. The part 93is extended as at 94:, the parts 89 90 and .9394 being formed with a chamber 96 therebetween, which chamber is connected to the'interior of the cylinder by a passage 1 95 formed about the parts by the space between the parts 89 and 9st.

The flanged part 89 is preferably provided with one or more exhaust openings 97 Itherethrough,

1 discharged through the opening 95 into the into the cylinder, the result being thata 101, 101 being extended parts, which shut off a portion of the space above the part 89 between the intake and the exhaust. The part 93 is preferably opened as at 98, so

that the spark plug 99, or its equivalent,

may be inserted into the cylinder, the pre ferred arrangement of the same being so that it does not extend quite to or below the lower edge of the mixing device. The operation of this form of mixer is as follows: The mixture is admitted through the intake port 87 and passes through the openings 91 into the chamber 96, whence it is cylinder and fired in the usual manner. The exhaust passes through the openings '97 and out through the exhaust port 88.

As'beforej mentioned, suitable valves at the same, the mixture being further mixed or -co-mingled at ,the time or after it passes mor eflicient mixture and charge is in the cylinder, when fired, g'iving a more efficient engine. 'The styles of the engines, valves,

etc., as shown in the drawings, are as before mentioned, merely for the purpose of illustration.

Having thus described my invention, it

is obvious that various immaterial modifications may be madej n the same without in-g said mixer at the intake port of the engine in the path of the ingoing mixture.
